Planning on getting the iPhone 5, but want to keep your SIM card? The new nano-SIMs that manufacturers are adopting will be even smaller than the micro-SIMs that most of us currently use. It's fairly easy to cut a regular SIM down to a micro-SIM, but because the nano-SIM will be thinner as well as smaller than the micro, cutting it down to size will require a little more work.

Whether you want to use it to keep your guests safe or just to see who's the most drunk, it's always fun to have your own breathalyzer at a party. We've seen DIY breathalyzers before, like this one by Craig Smith, but how about an Arduino breathalyzer?
Old newspapers come in handy for many different uses around the house, from birdcage liners to shipping cushioning and even a little fish cooking. But for backyard rocket scientists like Markus Bindhammer, they're more suitable as an ingredient for rocket propellant.

Believe it or not, it's possible to make your very own lava—if you have a furnace capable of heating up to 1,200 degrees Celsius, that is. Bob Wysocki and Jeff Karson started the Syracuse University Lava Project to study basaltic lava and give students a hands-on way (hypothetically, of course) to learn about it. Oh, and they also want to use it for art projects. Sign me up for that class! It all starts with 1.1 billion-year-old basalt gravel, which apparently anyone can buy. They put the gra...
As if the world needed one more reason to be obsessed with Shark Week, Volkswagen has teamed up with Discovery Channel to create this awesome "underwater car" that's actually a mobile shark cage.

As NASA nears the launch of another mission to the Moon in 2024, and a subsequent mission to Mars in the 2030s, augmented reality is increasingly being woven into the normal space operations to test various capabilities.
The signal bars in your iPhone's status bar are great visual indicators for knowing how good your cellular reception is, but they're not very accurate. Instead of showing the actual amount of signal you're receiving, they just give you a general range, and you'll have no idea if three out of four bars is actually a good connection or not. But there is a trick to see the real numbers.
Once again, Samsung has certified its flagship Note series with an IP68 rating. With this rating, the Galaxy Note 20 and 20 Ultra have some degree of dust and water resistance.
There's a new trend on Instagram Stories: People are making viral AR filters where images of popular characters from TV shows, movies, and other mediums shuffle above your head until one sticks. The filters range from Disney and Pokémon characters to Harry Potter and Friends, but you're not limited to just that because you can create your own "which are you?" filter.
Brute-forcing is an easy way of discovering weak login credentials and is often one of the first steps when a hacker finds network services running on a network they gain access to. For beginners and experienced hackers alike, it's useful to have access to the right tools to discover, classify, and then launch customized brute-force attacks against a target. BruteDum does it all from a single framework.
A lot of time can be wasted performing trivial tasks over and over again, and it's especially true when it comes to hacking and penetration testing. Trying different shells to own a target, and testing out privilege escalation commands afterward, can eat up a lot of time. Fortunately, there is a tool called One-Lin3r that can quickly generate shells, privesc commands, and more.
Web application firewalls are one of the strongest defenses a web app has, but they can be vulnerable if the firewall version used is known to an attacker. Understanding which firewall a target is using can be the first step to a hacker discovering how to get past it — and what defenses are in place on a target. And the tools Wafw00f and Nmap make fingerprinting firewalls easy.
In the technology space, there are certain brands you grow to depend on. Whether it's due to a long, multi-decade track record of success, or new innovations that blow you away, some tech names accrue a rare kind of brand equity with users that's difficult to earn.
If you find yourself with a roommate hogging limited data bandwidth with video games or discover a neighbor has invited themselves into your Wi-Fi network, you can easily take back control of your internet access. Evil Limiter does this by letting you control the bit rate of any device on the same network as you, allowing you to slow or even stop data transfer speeds for them completely.
For many, the stock version of Android is often considered the epitome of what the operating system should look and feel like by default. It's clean and clear of unwanted extra apps that come pre-installed with the system, provides a fluid and fast user experience, and runs on just about any device that has an unlocked bootloader to install a custom ROM with the stock version ready to go.
While Microsoft dominated the augmented reality news at this year's Mobile World Congress, a small AR startup we've covered in the past arrived in Barcelona, Spain, to unveil the next phase of its mission.
If you've grown bored of day-to-day hacking and need a new toy to experiment with, we've compiled a list of gadgets to help you take password cracking and wireless hacking to the next level. If you're not a white hat or pentester yourself but have one to shop for, whether for a birthday, Christmas present, or other gift-giving reason, these also make great gift ideas.
Smartphones and other Wi-Fi enabled devices send radio signals called probe frames to locate nearby wireless networks, which makes them easy to track by listening for their unique MAC address. To show how this kind of tracking works, we can program a NodeMCU in Arduino to sniff the air for packets from any device we want to track, turning on an LED when it's detected nearby.
Hackers and makers are often grouped under the same label. While hackers draw on computer science skills to write programs and find bugs, makers use electrical engineering to create hardware prototypes from microprocessor boards like the Arduino. We'll exercise both sets of skills to program a $6 NodeMCU to display the status of a Wi-Fi link via an LED, allowing us to monitor for jamming attacks.
Kali Linux is established as the go-to operating system for penetration testing, but in its default configuration, it's less than ideal for regular desktop use. While in many scenarios, a live boot or virtual environment can resolve these issues, in some situations, a full installation is better. A few simple changes can be made to a Kali Linux desktop to make it safer to use in this environment.
In the Android community, there's a lot of discussion about how display notches should be used. For some, hiding the notch is more appealing, but others feel that hiding it wastes screen real estate. Well, Essential just provided another solution that should satisfy both sides.

Shodan calls itself "the search engine for internet-connected devices." With so many devices connected to the internet featuring varying levels of security, the special capabilities of this search engine mean it can provide a list of devices to test and attack. In this tutorial, we'll use Python to target specific software vulnerabilities and extract vulnerable target IP addresses from Shodan.
